Autism Spectrum Disorders in Gender Dysphoric Children and Adolescents

Only case reports have described the co-occurrence of gender identity disorder (GID) and autism spectrum disorders (ASD). This study examined this co-occurrence using a systematic approach. Children and adolescents (115 boys and 89 girls, mean age 10.8, SD = 3.58) referred to a gender identity clinic received a standardized assessment during which a GID diagnosis was made and ASD suspected cases were identified. The Dutch version of the Diagnostic Interview for Social and Communication Disorders (10th rev., DISCO-10) was administered to ascertain ASD classifications. The incidence of ASD in this sample of children and adolescents was 7.8% (n = 16). Clinicians should be aware of co-occurring ASD and GID and the challenges it generates in clinical management

Antenatal corticosteroids and cardio-metabolic outcomes in adolescents born with very low birth weight

Exposure to antenatal corticosteroids (ANCS) is associated with adverse cardio-metabolic outcomes in animal models; however long-term outcomes in clinical studies are not well characterized. We hypothesized that exposure to ANCS would be associated with markers of increased cardio-metabolic risk in adolescents born with very low birth weight (VLBW)

Association between umbilical cord glucocorticoids and blood pressure at age 3 years

<p>Abstract</p> <p>Background</p> <p>Animal data show that decreased activity of placental 11-beta-hydroxysteroid dehydrogenase type 2 (11β-HSD2), which potently inactivates glucocorticoids (e.g. cortisol) to inert forms (cortisone), allows increased access of maternal glucocorticoids to the fetus and 'programs' hypertension. Data in humans are limited. We examined in humans the association between venous umbilical cord blood glucocorticoids, a potential marker for placental 11β-HSD2 enzyme activity, and blood pressure at age 3 years.</p> <p>Methods</p> <p>Among 286 newborns in Project Viva, a prospective pre-birth cohort study based in eastern Massachusetts, we measured cortisol (<it>F</it>) and cortisone (<it>E</it>) in venous cord blood and used the ratio of <it>F/E </it>as a marker for placental 11β-HSD2 activity. We measured blood pressure (BP) when the offspring reached age 3 years. Using mixed effects regression models to control for BP measurement conditions, maternal and child characteristics, we examined the association between the <it>F/E </it>ratio and child BP.</p> <p>Results</p> <p>At age 3 years, each unit increase in the <it>F/E </it>ratio was associated with a 1.6 mm Hg increase in systolic BP (95% CI 0.0 to 3.1). The <it>F/E </it>ratio was not associated with diastolic blood pressure or birth weight for gestational age <it>z</it>-score.</p> <p>Conclusion</p> <p>A higher <it>F/E </it>ratio in umbilical venous cord blood, likely reflecting reduced placental 11β-HSD2 activity, was associated with higher systolic blood pressure at age 3 years. Our data suggest that increased fetal exposure to active maternal glucocorticoids may program later systolic blood pressure.</p

Genitale chirurgie bij jongens met disorders of sex development

Het fenotype van jongens met een gestoorde geslachtsontwikkeling (DSD) varieert van (ernstige) hypospadie tot ambigu genitaal, vaak met enkel- of dubbelzijdig cryptorchisme. Müllerse structuren kunnen persisteren, zowel op het niveau van de - meestal cryptorche - gonade, in de vorm van een tuba en hemi-uterus, als in de vorm van een vergrote utriculus of mannelijke vagina. Persisterende Müllerse structuren bij een ondergeviriliseerde jongen moet nadrukkelijk onderscheiden worden van het zeldzame persistent müllerian duct syndrome (PMDS), waarbij een jongen met een normale penis naast intra-abdominaal gelegen testes, epididymides en vasa deferentia ook tubae en een uterus heeft. In dit artikel worden huidige behandelingsmogelijkheden toegelicht, inclusief de falloplastiek, een ingreep die momenteel niet in Nederland maar wel in België beschikbaar is. Langdurige follow-up van deze kinderen, inclusief evaluatie van psychoseksuele aspecten na de puberteit, is onderdeel van de multidisciplinaire behandeling

Psychological long-term outcome in intersex conditions

For decades, sex assignment in children with intersex conditions has depended more on surgical possibilities than on other criteria, since it was assumed that children are psychosexually neutral at birth. Adults with intersex conditions and professionals in the field have increasingly criticized this policy after the publication of studies suggesting that prenatal brain exposure to sex hormones determines gender development. Although prenatal brain exposure to androgens plays some part in the development of gender role behaviour, the current evidence is not in line with the idea of determination of gender identity through prenatal sex steroid exposure. Recent reviews on gender dysphoria and gender change in patients with intersex conditions show that initial gender assignment still seems to be the best predictor of adult gender identity
